A klaxon is a type of an electromechanical horn or alerting device. Mainly used on cars, trains and ships, it produces an easily identifiable sound, often transcribed onomatopoeically in English as "awooga". Like most mechanical horns, it has largely been replaced by solid-state electronic alarms, though the memorable tone has persisted.
United States Navy submarine tenders are U.S. Navy vessels, common throughout World War II, stationed in remote areas of the oceans to service submarines assigned to them. Such service would include providing fuel, food, potable water, spare parts, and some repair of submarine equipment and minor hull components.
Electrical Klaxon horn in 1910. Hutchison was concerned with increased automobile traffic in New York City. An early version of a vehicle speed alarm was not readily adopted. [12] Warning devices at the time were either bells or horns essentially derived from musical instruments. He realized that a more obnoxious sound would serve as a better ...

The US Navy has a total of 18 Ohio-class submarines which consist of 14 ballistic missile submarines (SSBNs), and four cruise missile submarines (SSGNs). The SSBN submarines provide the sea-based leg of the U.S. nuclear triad. Each SSBN submarine is armed with up to 20 Trident II submarine-launched ballistic missiles (SLBM).
The Type 209 (German: U-Boot-Klasse 209) is a range of diesel-electric attack submarines developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany.Five class variants (Types 209/1100, 209/1200, 209/1300, 209/1400 and 209/1500), including modifications thereof, have been successfully exported to 15 countries, with 68 submarines being built and commissioned to five different ...
The Benjamin Franklin-class submarines were built with the Polaris A-3 ballistic missile, and in the early 1970s were converted to carry the Poseidon C-3 missile. During the late 1970s and early 1980s, six boats were further modified to carry the Trident I (C-4) missile, along with six James Madison-class boats.
Communication with submarines is a field within military communications that presents technical challenges and requires specialized technology. Because radio waves do not travel well through good electrical conductors like salt water, submerged submarines are cut off from radio communication with their command authorities at ordinary radio frequencies.
